... that sent the professor back in time goes to the site in Scotland and explains what’s going on to all the other of archeologists and asks for a few volunteers to go back and bring the professor back to the present. When the volunteer’s go back they’re reappearing in front of some knight’s scares them so there two guides are killed and they are left alone in the 14th century trying to find the professor. While they are in the 14th century they prove true some of their hypothesis of what they thought that the area looked like. They go though all sorts of trouble but eventually bring the professor back and all is well. The whole story is ...
... and the financial cost of schizophrenia due to direct medical costs, lost productivity and Social Security pensions is between $30 billion and $48 billion according to Federal figures (American Pychological Association (APA), 1996). There are many theories about the aetiology of schizophrenia, but research has failed to pinpoint the origins. There is evidence that environmental pathogens (for example, viruses) are involved in the causation of schizophrenia. There is also evidence for a role of hereditary influences and obstetric complications on the incidence of schizophrenia. Furthermore, psychological influences have also been suggested as important in preci ...
... specific information about the valve. One of the more common found in industry is a gate valve. A gate valve is typically operated in the wide-open, or completely shut position. This type of valve is used where flow rates are not restricted. Globe valves are the second most common valve used I industry. A globe valve places a movable metal disc in the path of a process flow. This type of valve is most commonly used in the throttling service. Ball valves take their name from the ball-shaped, movable element in the center of the valve. The movable ball rotates to let flow pass through, and closes to stop it. Ball valves are not made for thrott ...
... in the history of the solar system may have stripped away lighter materials, making Mercury a very dense planet with an iron core extending outwards 4/5 of the way to the surface. Mercury bares a very similar resemblance to our moon because it has a lot of craters. The craters, which cover seventy-five percent of Mercury’s surface, were formed by huge rocks that smashed into the planet’s surface. The largest crater is called the Caloris Basin and it is 1400 km in diameter and is flooded with molten lava. Mercury also has many cliffs that are usually over 300 miles long and two miles high. The rest of the planet’s surface is smooth and may have been for ...
... and a half feet. The largest bird is a bird that cannot fly, the ostrich. Ostriches can stand almost eight feet high and can weigh near 350 pounds. Other extinct birds have been measured to stand over ten feet high. The evolution of birds is still being argued. Most people believe that birds evolved from reptiles. Because of birds mainly delicate bones, few fossils have been left behind for scientists to study. The earliest bird fossils come from archaeopteryx. The fossils that have been discovered from archaeopteryx include six partial skeletons and one single feather. Archaeopteryx , unlike modern birds, had teeth, a reptile like tail, and three claws on eac ...
... traits in children, a practice which has come to be called “negative .”2 In the late nineteenth century, a man named Francis Galton gave eugenic thought great emphasis.3 Yet it was not until Gregor Mendel’s theories on genetics were rediscovered by Charles Davenport in 1901 that the ideas of modern was given any credibility.4 Davenport conducted experiments that proved what Mendel had said years before in his laws of genetics. Davenport, however, took it another step. He extended Mendel’s laws to include characteristics such as pauperism, alcoholism, and the popular term of the day, “feeblemindedness.”5 Davenport also connected behavi ...
... lid at the outer corner of the . After passing over the , the liquid from the gland is drained into the nose through the tear duct at the inner corner of the . Heavy laughter or crying causes muscles in the upper lid to squeeze the lachrymal gland. This produces tears that flow too fast to be drained away. The lashes catch many flying particles that otherwise would enter the . As further protection, the lids automatically close when an object suddenly moves close to the . The eye is made of 3 coats, or tunics. The outermost coat consists of the cornea and the sclera. The middle coat contains the main blood supply to the eye and consists of the choroid, the c ...
... cloning saga also. In one method of artificial cloning used in plant breeding, cells are cut from a plant and placed in a flask with a nutrient medium. The cells grow and divide, forming embryonic tissues that are transferred to soil, where they produce complete plants. Grafting is another method of cloning used in Horticulture. Matching cuts are made in the stems of two plants, which are then fitted together so that their transport systems are in contact. The wounded area heals, and the two stems become a single physiological unit. All the McIntosh apple trees now in use and many other fruit varieties have been derived by grafting from single ancestral trees. " ...
... correlated with environmental degradation. Furthermore, it is fair to say that the MNCUs are more likely to have a more harmful environmental impact from growth and development, as opposed to the local corporations. This is because MNCUs may not be as knowledgeable as local corporations in resource utilization and land management. This also refers to the notion of Rthe locals know their land better than anybody elseS. The tropical rain forest of Brazil is a good example of this. The RindigenousS or the local people have a good understanding of how to extract and utilize its resources in a very sustainable manner. However when a multinational timber company com ...
... bursting charge of practice shells and bombs. Despite the fact that is called under one name, there are many different forms of . These are merely classified as how strong their reactions are, in other words, the size and power of their reactions. The most typical form of is the mixture of sulfur, charcoal, and potassium nitrate. Another form of this powder is known as the brown form, this is a mixture of saltpeter, charcoal, and sulfur. These pieces tend to look like little hexagonal or octagonal milk chocolate pieces. However these can be modified in a way to form a more harsh explosion. This method is known as grading, were powder size is modified to ho ...
